Simplify alloc.c static function decls

* src/alloc.c: Omit unnecessary static function declarations.
Don’t use ‘inline static’ as the C standard says that keyword
order is obsolescent.  Anyway, no need for ‘inline’ as compilers
inline without it well enough.

Make native helper functions static

These don’t need to be extern, even with -flto, since
their addresses are taken.

* src/comp.c (directory_files_matching) [WINDOWSNT]: New function.
(eln_load_path_final_clean_up) [WINDOWSNT]: Use it.
This removes the need for internal_condition_case_5.
* src/eval.c (internal_condition_case_3)
(internal_condition_case_4, internal_condition_case_5): Remove.
The first two were never used; the last only in now-removed code.

Remove sanitize_window_sizes

* src/window.c (sanitize_window_sizes): Remove; no-longer-used.
A previous refactoring moved this to Lisp without removing the C code.

Pcomplete: Better obey `completion-at-point-functions`

Functions on `completion-at-point-functions` should not modify
the buffer.  Pcomplete itself mostly abides by this but Eshell's
use of it doesn't.  Try and catch those cases.  Also fix one of
those cases.

* lisp/pcomplete.el (pcomplete-allow-modifications): New var.

machine, 2.2× faster excluding GC).

Remove some early-bootstrap dependencies for `advice`

The dependencies between `advice`, cl-generic`, `bytecomp`, `cl-lib`,
`simple`, `help`, ... were becoming unmanageable.
Break the reliance on `advice` (which includes making sure the
compiler is not needed during the early bootstrap).

* lisp/loadup.el (advice, simple): Move to after `cl-generic`.

Put bytecode stack frame metadata in a struct

Using a plain C struct instead of type-punning Lisp_Object stack slots
makes the bytecode interpreter code more type-safe and potentially
faster (from better alias analysis), and the special-purpose accessors
are no longer needed.  It also reduces the stack requirements when
using 64-bit Lisp_Object on 32-bit platforms.

* src/bytecode.c (enum stack_frame_index)
(sf_get_ptr, sf_set_ptr, sf_get_lisp_ptr, sf_set_lisp_ptr,
sf_get_saved_pc, sf_set_saved_pc): Remove.
